BAND-TYING GAUGE.

Application filed April 5,

To all 'ui/'1,0112 'it 71mg/ concern.

Be it known that we, MALcoLM CURRY, a citizen of the. United States, and resident of Scarsdale. in the county of Westchester and State of New York, and ALBERTA COOK, a citizen of the United States, and resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Band- Tying Gauges, of which the following is a specification.

This invention relates to improvements in gauges for use. in tying driving bands of band-driven machines with a regulated tension, the improved device being' especially adapted for use in tying the spindle driving bands of spinning or twisting frames.

rlthe invention has for its object to provide a simple and durable device of the character set forth so constructed as to decrease t-he labor and time required in tying bands.

In the thawing-s:

Fig. f) a section on the line 9-9 of Fig. 10; and

Fig. 10 a fragmentary side elevation showing a modified form of pivotal connection' and tension regulating spring.

The device comprises an attachment and positioning member 1 bifurcated at its lower end to form a voke 2 in which the lower end of a swinging tension-regulating member 3 is pivotaliyl held byaf suitable pivot pin 4. horizontal bracket 5 is formed integrally with yoke at the opposite side of member l from that at which member 3 is located, said bracket being provided with an elongated aperture 6 adapted to receive the 1921. Serial N0. 458,862.

lower end of the spindle bearing or bolster 7 which depends below the rail 8 of the spinning frame. Aperture 6 is preferably of the same width transverselyT of bracket 5 as the diameter of the lower part of the spindle bearing and is rounded at its ends to correspond with the curvature of the cylindrical bearing.

Bracket 5 is provided at one end with an abutment or shoulder 9 adapted t0 be engaged by 4an abutment or shoulder 10 on the lower end of member 3 to limit the eX- tent of movement of the free upper end of member 2 awa-y from member 1. Member 3 is normally swung away from member 1, to the limit of movement permitted by the knuckle joint connection between the members, by a helical tension-regulating spring 11. One end 0f spring 11 is confined in a socket 12 in member 1 and the other end thereof is confined in a socket 13 formed in an externally threaded plug or nut 14 screwed into the outer end of a` cylindrical bore or passage 15 extending through member Member 3 is formed with a. cylindrical enlarged portion 16 intermediate its ends provided with the bore 15. Nut 141 is provided with a socket 17, preferably of hexagonal or other form requiring a special wrench or tool for adjusting the nut to vary the tension of spring 11.

Member 1 is provided intermediate its ends with traneversel)v eizteufing channel or recess 1S adapted to receive the outer eflgrof the rail. 8 of the spinning frame, and is provided at its upper end with an integral bracket 19 located over bracket 5. The bottom wall of channel 18 is preferably beveled along its ou..." edge to facilitate the engagement of member 1 with the rail Bracket 19 is cut away at its outer end to forni a notch or recess 2O adapted to receive the spindle bearing` T at a point between rail 8 and the spindle whorl. A. plate is detachablv held to the upper face ot' bracket 19 by screws E23. the outer end of the plate being' cut-away to form a notch o1' ref 24 of the same size and shape as the rece the bracket. The ner ends of recesses 'T20 and .21 are preferably curved on the same arc as the surfaceof the spindle bearing T and the sides of the recess adjacent the mouth thereof are preferably iared outwardly as shown to facilitate the entrance of the spindle bearing into said recesses. The upper tace ot bracket 19 is cut away along opposite sides thereoiI as shown at to form channels under plate 22 in which are confined the side arms et' a U-shaped spring 267 the transverse part oi which is clamped against a shoulder at the inner end ot' bracket 19 by the oli a screw 27 threaded into the bracket. l

Thei'ree ends of the side arms ot spring 26 are bent inwardly toward each other and then outwardly to form two triangular end portions 28 between which the spindle bearing may readily pass in either direction and which serve to grip the bearing and fricf tionally hold member l thereto. Spring 26,

recesses 2O and 2a, and elongated opening G in Ybracket 5 serve to align the device with t e spindle, and detachably but firmly holding the device in Vengagement with the spindle and rail." The engagement or rail 8 inl channel 18 serves to position the device at the proper point longitudinally et' the spindle and also to prevent swinging ott the device around the spindle bearing.

Member 3 is provided at its upper end with an' inwardly extending arm2$l provided at its inner end with an upwardly extendinghook or projection 30 around which the'spindle driving band is passed in tying lthe band, as indicated in dotted lines in Figs. 1 and 2. The inner end ot arm 29 isA beveled downwardly and outwardly to form `a cam surface 31 adapted to rideI over the upper yend of a verticallj/,f slidable latch 82 and depress said latchy against the pressure of a spring 33 when member 3 is swung toward member 1. Arm'29 is provided with a notch 34 into which the upper end ot latch bar 32 is adapted to snap to lock member 1 against movement in either direction after the same is swung a predetermined distance toward the spindle.

Latch 32 is confined in a channel 'formed in the inner 'face of a block 35 which is held against the inner face oi member 1 by two screws 36. A. pin 37, heldy to block 35 and engaging in a slot 38 in latch bar 32j serves to limit the sliding movement oit the latch bar.4 Spring 33 is partly housed in a vertical bore 39 "in block 35 and the upper end ot the spring surrounds a depending lug 10 lformed on one of a pair ot finger pieces 41.1 with which the upper end ot the latch is provided An angular sheet metal band castolf lever /12 is pivotally held by pin 4:3 to the upper end" oit member The lever L12 is of channel form in crosssection, one arm thereof being adapted to embrace arms 29'01"" member 3 and the other arm thereof being adapted to embrace the upper portion Koi `member 3. The transverse web of the horizontal arm ctie-ver l2 `is cut away at the tree end of said arm-and the vertical side webs ot said -cut away portion of the lever arm entend knotted together without danger Vot along opposite sides ot hook 30. as shown at 414e, so as to liit the tied band off said iook when the depending arm or' the lever is swung inwardly toward member She operation of vtying a band is as follows:

The lower end of spindle bearing 7 is engaged in aperture! 6 in bracket 5, and meniber 1 is then swung toward the spindle to engage the outer edge of rail 8 in channel 1S and cause the upper end of bearing 7 to be clamped in' registering recesses 20 and 24k in bracket 19 and plate 22 by the U-shaped spring 26. The spindle driving band is then passed around the driving pulley or cylinder and ts endsbrought around hook 3() over the end portions 441 oit' the'cast-oii lever 12,'as indicated inFig. 1. The knot is then partly formed and pull exerted to contact the loop thus formed by the band. The pull or' the looped band swings member `8 towards memberl as the loop is contracted until latch 32 snaps in notch 34 in member 1. The band is then at the desired tension and, as member 3 is locked against return movement, the Vends Yor' the -band may bey Acompletely increasing or relieving the tension and without eiort von the part of the operative to hold memb v`When the knot is completed and the' loose ends of the band clipped off, the operative presses the depending arm of lever-'A12 toward member 8, whereupon the end portions 14e oi said lever swing upwardly and litt the band oil hook 8O to permit the band to snap into the ygroove in the spindle whorl 21. Latch 32 is then disengaged from notch Sil by pressing downward `on one ot the finger pieces 41, to permit member 3 to swing outwardly to its normal position, andI member 1 is then disengaged from the spindle bearing. 7e have iound in practice that the kick of spring` 11, when latch 32 is released, is suilicient to automatically disengage the device from the'spindle, so that the operative may simply depress the latch and let the device drop into his hand;

ln Figs. 9 and 10 a modified form of pivotal connection between members 1 and 3 is shown. and also 'a modified form of spring and means for varying t-he tension oit the spring. ln this construction. membersv l and 3 are provided adjacent their lower ends with transverse grooves 415 in which the shank ot a pivot bolt i6 engages, the members being clamped against oppositesides ot the bolt-by the tension regulating spring i7 so as to have limited rocking movement about the boltas a'pivot. Spring 47 compris ing a split Vring of resilient metal the ends of which are adapted to bei engaged in notches 1S Jformed in the outer sides kof 'arms-0r YeX- tensions L@and 5 0 of membersl and'which depend below pivot bolt 46; :Each ar`m`49 er 3H against the pressure of spring 11.

and is provided with a plurality of notches so that the ends oitspring l? may be engaged with the arms different distances from the pivot bolt to vary the pressure required to move member 3 from the position shown in Fig. l to the locked position shown in Figs. i? and 9. The arms 49 and 50 are adapted to abut against each other to limit the outward swinging movement of member 3. The ends of spring e7 are notched to provide fingers 5l which engage the edges of arms 49 and 50 and prevent sidewise movement of spring 47.
